Appalling customer service

I called in April enquiring about a payment holiday and was told I do qualify for one on my vehicle not on my bond account, however I requested figures in terms of interest and the next instalment date and amount before we can proceed and till date that was not sent through. I want to trade in my vehicle and I need a quote sent to me as to how much is my next instalment as soon as possible. Brand promise is very crucial for a business, you promise something you try by all means to provide it.
